Family photos for identification - Kandos NSW

Can you help Amanda Rowe identify these photos?

Amanda says:

"I'm sharing these photos in the hope of identifying some of the people. They are from the collection of my grandfather, Lindsay Wilson, and they are taken in Kandos. Many of the photos appear to be taken in front of the Railway Hotel, which is where my grandfather was living while he worked at the cement works in Charbon. My guess is that they were taken either in the late 1920s or the early 1930s and the men could be people from the town and/or colleagues, who may or may not have been from Kandos. It's a long shot, but just wondering if any of the men can still be identified."
